Last week, we wrote about the BSOD issue that Crucial's M4 SSDs were experiencing. After 5184 hours (yes, that's the specific number) of active use, the SSD started to cause blue screens of death (i.e. BSODs) every hour or so. Originally, the fix was scheduled for next week but fortunately Crucial was able to release the firmware update yesterday. The firmware version is 0309 and can be downloaded here. It's recommended for all Crucial M4 SSDs, even if you are not experiencing the BSOD issue as it will prevent it from happening.

The earliest reports indicate that the update does fix the BSOD issue, although it will take at least several days before we can be sure of that. User Vivio at Crucial forums has already run benchmarks and the update appears to be a pure bug fix, as the performance is the same as with the older 0009 firmware (see Anand's review).

You realize crucial also has a utility that lets you do that right? Get better information before looking like an idiot fanboy. Also, anyone that knows the risk of firmware updating knows to not do it that way anyway. Reply

"Burning an ISO is an inconvenience and a waste of a disc in comparison."

I completely disagree. Firstly you can use YUMI or similar Linux tool and make a bootable ISO on a USB stick. Second updating in a DOS/Linux environment is far less likely to go wrong than updating via Windows. Samsung have just released a new firmware for their 830 series with Windows flashing possible through their Magician software or you can burn/mount an ISO. I chose the latter and used a CD-RW and it worked without issue. There are many reports of people who chose the WIndows method being greeted with BSOD's and having to reflash using the ISO.

Granted if Windows flashing is offered, it should work. But I think all experienced users would take DOS/Linux flashing over Windows flashing anyday.Reply

I'm glad their are people that actually know what the hell they are talking about posting here along with the morons with half-wit information and input. Thanks. USB booting is great, and no wasting an optical disk on 2MB of data never to be used again. (unless you have a RW, but the USB stick is still going to be faster and easier)Reply

I had this exact problem last week with my BSODs on my 256gb Micron C400. It was a strange problem to troubleshoot because at first iaStor.sys (running under System) would max out the CPU, freeze the computer, and then after a few minutes the OS would finally bluescreen.

Thought I was gonna have to replace the drive. But after Micron's firmware 0309 update, all good!! Yes I know they're the same, relabeled drive but figured I'd through it out there.Reply
